DEVICE FOR SAWING LAST-BLOCKS.

Specification of Letters Patent.

Patented Sept. 3, 1907.

Application filed Deoember'17. 1906. Serial No. 348,154.

To all whom it may concern:

Be it known that 1, HARRY J. .TAQUITH, a citizen of the United States ofAmerica, and a resident of Boston, in the county of Suffolk and State ofMassachusetts, have invented certain new and useful Improvements inDevices for Sawing Last-Blocks, of which the follow ing is aspecification.

This invention relates to apparatus for simultaneously sawing slots inthe two parts of a hinged lastin which subsequently the hinged plate maybe inserted to connect the two parts.

When in the manufacture of lasts the last is divided after it leaves thelathe, the two parts of the divided last being intended to be connectedtogether subsequently by a hinged plate, it is obvious that it isessential that the slots in the two parts in which the hinge plate isinserted should be in exact relation one to the other and it is toprovide an apparatus which will simultaneously and accurately saw theseslots in the two parts of the last which is the'object of the presentinvention.

The invention consists in certain novel features of construction andarrangement of parts which will be readily understood by reference tothe description of the drawings and to the claims to be hereinaftergiven.

Of the drawings: Figure 1 represents a front elevation of a circular sawand attachment therefor e1nbody ing the features of the presentinvention. Fig. 2 represents a plan of the same. Fig. 3 represents aside elevation of the same. Fig. 4 represents a front elevation of theupper portion of the same showing the adjustable tables at differentheights. Fig. 5 represents an enlarged plan of one of thework-supporting slides. Fig. 6 represents a section through thework-supporting table and showing in elevation thereon a work-supportingslide. Fig. 7 represents an end elevation of said slide, and Fig. 8represents a section of a hinged last provided with slots cut into thetwo parts thereof by this improved apparatus.

Similar characters designate like parts throughout the several figuresof the drawings. 3

In the drawings-10 represents a standard adapted to be bolted to thefloor and having mounted in a bearing 11 therein a shaft 12 havingsecured to one end thereof a fixed pulley 13 and loose pulley 14 and atthe other end a pulley 15 which connects by the belt 16 with a pulley 17mounted upon a revoluble shaft 18 mounted in bearings 19. JThe outer endof this shaft 18 is pro- .vided with a circular saw 20 driven thereby.The

front of the standard 10 is provided with suitable guides 21 in whichare mounted the vertically adjustable tables 22 each of which isprovided with a slot 23 through which extends the clamping bolt 24 toclamp either of the tables in adjusted position. Bearing against theunder face 25 of each table is an adjusting member 26 threaded to cars27 extending from the front of the standard 10, said threaded members 26being operated by means of the hand wheels 28. i

It is obvious from an inspection of the drawings that either of thetables 22 may be adjusted vertically and retained in adjusted positionby means of the clamps 24 while the adjusting members 26 will preventsaid tables from moving longitudinally on the standard 10. Each of thetables 22 is provided with a dovetailed groove 29 in which is mounted aslide 30 adjustable toward and from each other in the plane of movementof the circular saw 20.

Each of the slides 30 is provided with'a scale 31 with which cooperatesan index 32 secured to a bracket 33 movable transversely of said slidein a depression 34 in the upper face thereof. The member 33 is providedwith a slot 35 through which the clamping bolt 36 extends to clamp themember 33 in its adjusted position. This position is regulated by meansof the index 32 cooperating with the scale 31.

The upright portion of the member 33 is provided in one case with a pin37 extending therethrough and held in adjusted position by means of theset screw 38, the purpose of said pin being to enter a hole boredtransversely of the toe portion of the last and support this part of thelast during the operation of sawing. Into the other end of the holeextends a corresponding pin 39 secured by the set screw 40 in theupright portion of a slidable member 41 slotted at 42 and prevented frombeing displaced from the depression 34 by means of the headed bolt 43.The supports for the heel portions are similar to those for the toeportion with the exception that the upright members of the brackets 33and 41 are provided with a pair of pins 44 extending toward each otherand entering the holes 45 bored transversely of the heel portion for thepurpose of securing the hinge plate 46 therein by means of the holdingpins 47 ex tending therethrough. This plate 46, when the last iscompleted is hinged to the toe portion by means of the holding pin 48,extending through the hole 49, and it is this hole 49 that, during theoperation of sawing, the

supporting pins 39 extend into. The inner end of each of the slides 30has secured thereto a flexible member 50 which passes over a pulley 51and is secured to the eye bolt 52 adjustable in the member 53 and heldin adjusted position by means of the nuts 54 on either side thereof.

The member 53 is connected by the link 55 with a treadle 56 pivoted at56"- to ears extending from the front of the standard 10. By depressingthe treadle 56 it is obvious that the slides will be moved toward eachother until they bear against the adjustable stops 57 secured inadjusted position by means of the clamping screws 58 threaded to thetable 22 and extending downwardly into the groove 29 in said table inthe path of said slide. To the outer end of each of the slides 30 issecured a flexible member 60 extending over rollers 6162 and havingsecured at the opposite ends a counterweight 63 which is adapted toreturn the slides to their normal separated positions when pressure isremoved irom the treadle. The outward movement of said slides is limitedby means of the pins 64 extending upwardly from the table 22 into thegroove 30 in the path of movement of said slides. The slide adapted tosupport the toe during the operation of sawing is provided with anadjustable pad 66 threaded to said slide so that it has a verticaladjustment to adapt it to support the toe part 67 of the last and holdit in any angular position about the a ds of said supporting pins 39.

It is obvious that with different shapes of lasts the angle in which thetoe part is held during the operation will be greatly varied and it isalso obvious that with different shapes of lasts sometimes it will bedesirable to have one table adjusted to a greater or less height thanthe other and provision is therefore made to accomplish this.

When one table has been adjusted in this manner at a greater or lessheight than the other it is necessary to take up the slack in theflexible member 50 by means of adjusting the threaded eye 52 which maybe done by this means or any other well-known means. To each uprightportion of the adjustable member 33 is adjustably secured the angularguide plate 70 provided with a slot 71 through which extends theclamping bolt 72 by which said plate may be clamped in any adjustedposition vertically of the upright portion of the work-supporting member33. This plate70 is provided with a scale 73 with which co-acts an index74 on the upright portion of the member 33. The inclined edge 75 of saidplate 70 serves as an inward guide for the sides of two parts of thelast and when each of the members 70 has been adjusted vertically to thesame point it is obvious that the slot 76 to be cut in the two parts ofthe last will correspond accurately so that when thehinge plate 46 isinserted therein and the two parts joined together thereby the face ofthese two parts will conform and be flush one with the other. The pins39 are made removable with their supporting members so that in. case ofbreakage they may be readily removed and new ones inserted therein.

In the operation of the machine aiter the various adjustable membershave been adjusted for the size and shape of the lasts to be operatedupon the operator moves the slides 41 to the front separating them fromthe adjustable guides 33 which when once adjusted are secured to a fixedposition by means of the clamp screws 36. When thus separated the twoparts of a last block are taken and the heel portion placed upon thesupporting pins 44 and the toe portion on the supporting pin 39 allowingthe toe end thereof to rest upon the adjustable pad 64. The operatorthen moves the members 41 toward the rear causing the pins 39 and 44thereon to enter respectively the other end of the openings 49 and 45.The slides 41 are not clamped when moved in but simply are freelyslidable along the groove 34. When the heel and toe portion have beenmoved bodily against the inclined edge 75 of the plates 70 the operatorplaces his foot upon the treadle 56 and depresses it to cause the slides30 to be moved toward each other until their. inner i'aces abut theclamps 57 previously ad justed to any desired position, as hasheretofore been described. This movement of the slides 30 inwardly inthe plane of movement of the saw 20 to which power has been applied tocause it to revolve at this time causes the saw to enter simultaneouslythe heel and toe portion and cut in each of these parts a slot 80 and81, as shown in Fig. 8, suitable for the reception of the hingeconnecting plate 46 as shown in said figure. As soon as the slides reachtheir limit of movement by coming in contact with the adjustable stops57 the sawing is completed and the operator removes his'ioot from thetreadle and permits the weights 63 to return the slides into theirnormal positions. When this has been done the supports 41 are movedalong the depressions 34, thereby removing their pins 39 and 44 from thetoe and heel parts of the lasts. These parts of the last may then beremoved from the supporting pins 3944 of the rear members 33 and a newlast placed in position thereon and the operation repeated. It isbelieved that without any further description the operation of theinvention will be thoroughly understood and that the advantages of anapparatus of this nature wherein articles of irregular iorms such aslasts may be supported on slides adapted to simultaneously move towardeach other into position to be operated upon by a revoluble circular sawwill be fully apparent.
